SMOKE AND SPARK ARRESTER AND CONSUMER.

SPECIFICATION forming part of Letters Patent No. 483,055, dated September 20, 1892.

Application filed January 13, 1892. Serial No. 417,915. (No model.)

To all whom it may concern.-

Be it known that I, EDsoN J. HADLOCK, of Big Spr1ng,in the county of Howard and State of Texas, have invented a new and Improved Smoke and Spark Arrester and Consumer, of which the following is a full, clear, and exact description.

My invention relates to improvements in smoke and spark arresters and consumers, such as are adapted for use on locomotives; and the object of my invention is to produce an apparatus of the character described which may be economically applied to a common locomotive and which will cause the smoke and sparks to be arrested and consumed, thus effecting a saving of fuel and preventing the sparks from setting fire to the surrounding property.

My invention is an improvement on the apparatus for which I obtained Letters Patent of the United States April 7, 1891, No. 450,012, and also on the apparatus for which I applied for Letters Patent of the United States May 29, 1891, Serial No. 394,514, said application having been allowed August 10, 1891.

My invention consists in certain features of construction and combinations of parts, which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a broken side elevation, partly in section, of a locomotive provided with my improved apparatus. Fig. 2 is a cross-section of the same on the line 2 2 in Fig. l, and

Fig. 3 is a broken plan view of the same.

The locomotive 10 is of the common type, having an extension-front 11, from which extend rearward on each side of the locomotive the return smoke-pipes 12, which have valvecontrolling openings into the fire-box, as shown at 18, and which at their rear ends connect by couplings 14., with apipe 15, coiled within the tank of the tender 16, and the pipe 15 opens, as shown at 17, into a chute 18, leading to the ash-pit. The chute has a water-holding receptacle 19 in the lower part thereof, and the water is pumped from this receptacle by a pipe 20, leading from the Water-receptacle to the filtering apparatus in the tank of the tender.

In front of the smoke-box is a swinging damper 21, operated by a lever 22, extending into the locomotive-cab, and beneath the ashpit is a sliding damper 23, connecting by a rod 24 with a lever 25, which also extends into the cab, so that it may be easily operated.

Connected with the steam-dome of the locomotive are pipes 26, which at their lower ends 50 struction shown in my former patents referred to, except that the smoke-pipes connect with the extension front instead of with smokeboxes in the rear thereof. The extension front 11 is divided transversely, so as to form a rear smoke-box 27 and a receptacle in front of it by a partition 28, which partition has centrally therein a swinging door 29, which enables the interior of the smoke-box to be reached when necessary, and the door should be arranged so as to make an air-tight joint when closed and prevent it from interfering with the draft. Opening from the upper portion of the smoke-box 27 is a short stack 30, which connects by means of an elbow 31 with a box 32 in front of it, which box connects with the extension front and has an escapestack 33 opening from its upper portion in front of the elbow 31. In the bottom of the box 32 is an /\-shaped deflector 34, which is suspended from its edges by means of suitable bolts 35, and this deflector permits the smoke, sparks, and cinders which issue from the elbow 31 to pass downward into the extension front, and the cinders and sparks cannot rise, as the deflector will stop them; but 5 the very light smoke, which is substantially freed of carbon, will escape through the stack 33. In the bottom of the extension front 11 is a hopper 36, which ranges slightly forward and which is closed by a cover 37, and by means of this hopper the cinders may be withdrawn from the extension front when the latter has become full, or nearly so.

The operation of the apparatus is as fol- The pipe 26 is con- 55 lows: As thesmoke and other products of combustionissue from the boiler-fines into the smoke-box 27 they will pass upward through the rear stack 30 and forward through the elbow 31 to the box 32. Here the light smoke, which contains no carbon or substantially none, will pass upthrough the escape-stack 33, while the other products of combustion will pass downward over the deflector 34 and into the extension front 11. The deflector will prevent the said products from returning, andthe heavier and worthless products-such as the cinderswill settle in the extension front, while the smoke and lighter matter will pass back through the smokepipes 12 into the fire-box and be consumed. These smoke-pipes 12 may connect directly with the fire-box or the products may be carried around through the pipe in the tank, as desired.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent The combination, in a locomotive having a transversely-divided front extension 11, of a box 32 over the forward compartment, a deflector at the bottom of the box and upper part of saidcompartment and having its edges spaced therefrom to permit communication between the two, a stack 30, extending upward from the rear or smoke compartment and discharging through an elbow 31 into the top of said box, a stack 33, leading from the top of box 32 in front of stack 30 and of greater diameter than the latter stack, and the pipes 12, leading from the forward compartment rearwardly into the fire-box above its fuel-space, substantially as setforth.
